Recently the BA award booking site has been throwing up this error whenever I select Qantas domestic flights
"Sorry there is a problem with booking this journey online. Try selecting other flights"
This is despite the site offering numerous flight alternatives (all of which are also available on QF's own award site) but when the desired flight is selected, the error is shown.
The flights are true QF flights, not Jetstar or Qlink etc, so doesn't appear to be a problem with affiliates.
Seems to happen for all domestic flights i.e. MEL-SYD, but if their is a domestic leg before an International flight it shows the Avios and GBP for the flight, i.e. ADL-MEL-HKG does not produce the error.
Does anyone else have this problem, or know of a solution other than the ubiquitous call support ?
